Overview
The LMV393IDR is a dual general-purpose low-voltage analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and features an open collector/open drain output type. The device exhibits a typical response time of 200 ns and draws a maximum operating supply current of 100 uA. Key electrical parameters include a maximum input offset voltage (Vos) of 7 mV, an input bias current (Ib) of 250 nA, and an input offset current (Ios) of 50 nA. Each channel provides an output current capability of 23 mA. The component is housed in an SOIC-8 surface-mount package and supports an extended industrial temperature range from -40°C to +125°C.
Feature Summary
- Dual-channel architecture designed for general-purpose low-voltage applications
- Open collector or open drain output configuration for flexible interfacing
- Extended industrial temperature operation spanning -40°C to +125°C
Applications
- Battery-powered systems requiring low quiescent current
- Threshold detection circuits
- Voltage monitoring applications
Procurement Notes
Verify the specific suffix 'IDR' corresponds to the SOIC-8 package with tape-and-reel packaging as documented. Confirm that the manufacturer is Texas Instruments and that the RoHS compliance status matches current regulatory requirements. Ensure the ordering part number aligns with the datasheet specifications for the dual comparator variant to avoid substitution errors with similar family members.
Selection Notes
Select this component when a dual comparator with low supply voltage operation between 2.7 V and 5.5 V is required. The LMV393IDR is suitable for designs prioritizing low power consumption with a 100 uA supply current. Consider the 200 ns response time and 7 mV input offset voltage for precision requirements. The SOIC-8 package facilitates surface-mount assembly in compact layouts.
Part Context
The LMV393IDR belongs to the LMV393 series of general-purpose low-voltage comparators from Texas Instruments. This series includes single, dual, and quad variants designed for battery-operated equipment. The device utilizes a CMOS input stage to achieve low power consumption while maintaining adequate speed for many standard applications. It serves as a cost-effective solution for signal conditioning and threshold detection in consumer electronics.
Replacement Considerations
LMV393IDRG4 is a verified equivalent part number within the same product line.
